Beau Belgrave 5dbd04eddb tracing/user_events: Allow events to persist for perfmon_capable users ... There are several scenarios that have come up where having a user_event persist even if the process that registered it exits. The main one is having a daemon create events on bootup that shouldn't get deleted if the daemon has to exit or reload. Another is within OpenTelemetry exporters, they wish to potentially check if a user_event exists on the system to determine if exporting the data out should occur. The user_event in this case must exist even in the absence of the owning process running (such as the above daemon case). Expose the previously internal flag USER_EVENT_REG_PERSIST to user processes. Upon register or delete of events with this flag, ensure the user is perfmon_capable to prevent random user processes with access to tracefs from creating events that persist after exit.
